OVERSE All/LING SEWING-MACHINE Specification oz" Letters Patent.

Application filed April 13, 1907. Serial No. 368,035.

T o all whom it may concern:

Be it linown that l', ALFRED GRIEB, a citizen of the United States,residing at Elizabeth, in the county ol Union and State of New Jersey,have invented certain new and useful Improvements in OverseamingSewing-Machines, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates tocertain improvements in the overseaming sewingmachine forming the subject of my application Serial No. 321,952, iiledJune 16, 1906, and has Afor its objects, among others, to improve theconstructive features of the trame so as to permit of a more effectivearrangement of the operative parts, to insure convenience in assemblageol the latter and removal for repair or replacement, to improve thee'l'lectiveness of operation and durability of the parts subjected tothegreatest wear in operation, and to improve the general appearance andconvenience of manipulation of the machine. l

In its preferred form, the machine is provided with a rectilinearlyreciprocating nee- (lle and two cooperating thread-carrying loopers ortliread-carriers by which a threethread overseam is produced.

As regards certain ot its characteristic features, the presentimprovement is not limited to any particular type of loopers, as thiswill depend largely upon the hind of overseam desired, and thc ternithreadcarricrs`7 as used herein is employed in its broader sense toinclude thread-loop handling implements of any suitable formcoperat-ing` with the needle in the production of stitches.

l/Vhile the character of the tension and stitch-setting devicesdetermines the position of interlock ol' the threads, such members arepreferably designed to locate such interlorl. along the edge o1" thei'naterial inelosed by the overseain so as to provid(` a species ofbraid to cover sii zliextieine edge.

In the machine disclosed in my prior application, a brael.et in theforni ot' a tlat plate afl'ording the bearings for the inclinedmedle-bar extended forwardly lrom the back ol. the machine and carriedthe l'ulcrumpin for the needle-aetualing roch-lever, thc rearwardendet/mich was connected with the eccentric-rod embracing an eerentric;upon thelmain-shaft. 'lhe parallel relation i ot the needle-actuatinglever with the l'nii'etion.

y and its strap and harsh driving relation between the eccentricy`center ol' its length clined needle-bar,

lever and other operative parts thus made it necessary to employ aseries of closely adjacent actuating eceentries upon the mainshal't forimpartingthe requisite motion to such parts, and the necessary use ot aneccentric tor' imparting the requisite long throw to the needle-barinvolved the employment of an eccentric of large diameter 1n conjunctionwith a needle-actuating lever having a relatively short arm connectedwith the eccentric-rod for production of such mo- This was found inpractice to produce PatentedAug. 24, i909.

an excess of friction between the eccentric to involvev a somewhat rodand the needle-actuating leverwhich produced excessive wear of suchparts and noise in the operation of the machine at high speedsconsequent upon such wear.

By the-present improvement I have replaced the needle-bar-supportingbracket, disposed parallel with the line of feed, by an overhangmbracket-arm arranged longitudinally of t ie main-shaft and providing aninclined transverse fulcrum for a longitudinally disposedneedle-bar-actuating lever, thus affording an arrangement involvin alonger lever fulcrumed substantially at the for actuation from a oint 1nthe main-shaft distant from the wor -engaging members of thestitch-forming, feedlng and trimming devices. By this means I am enabledto provide a crank of small diameter upon the main-shaft having therequisite throw for imparting the re uired reciprocating movements tothe nee le-bar so as to reduce to a minimum the friction of themechanism, to provide easier and .quieter movements ol' the mechanismand to materially increase the durability of the latter. By the newlocation of the needle-bar-actuating lever the latter is so arranged asto permit the easy removal of the cutter and presser-loot levers, andthe latter may be alsscmbled and .removed independently and withoutdisturbing or atlectingthe other operative parts of themachine.

The upright portion of the bracket-arm is detachably secured upon thebed of the machine by screws in a Well-known manner, and its lateralportion allords a suitable support l'or the inclined needle-bar leverfulcrum-pin. The laterally. extending portion of the liracket-arm istwisted and )rovide-d with an inclined head sustaining t ie similarlyi'nbetween which and one of the bearing bosses foi the vi'ul( :rixnipinof the needle-barectuating ver is interposed the forward arm of theletterheving the usual linl; connections with va collar upon the needie-bar, whilea. renrwgtrdly exten seid iever is disposed upoirthc 'oppoof the bracket#erm` andlis'c end'ol "theA pitn f embreces the actuatingA shcii This peciiliarir not er( n eretive i'nenibeji edle. mech enisin,but yprcwvides a rece/ss io `eetive end' portion of the needle-ba inglever anfl the telre-up device of whirl same constitutes an operativemember also 'its connections with the needle i c materelly' improves thee,ppearer1ce`of the machine.
